Testing Full-Scale Houses Subjected to Simulated Extreme Wind Loads

Abstract

The response of wood-frame roof, wall, and floor systems and the effect of connections on the interaction between these systems is complex. Full-scale testing is an effective means to investigate how load paths develop and are maintained up to failure. The benefits of full-scale testing are demonstrated by tests of a corrugated fibreboard shelter roughly 16 by 20 ft in plan that was subjected to simulated hurricane-force wind loads. It performed well but failed prematurely where tension was applied through the thickness of the corrugated fibreboard and where the quality of construction was imperfect. Theoretical analyses might have identified the first of these weaknesses but would not have illuminated the second. The test results were also useful to validate the results of finite element analysis of the shelter. as shown in Figure B. The design and effectiveness of the testing apparatus and instrumentation will be briefly described, and the specification for a more effective test facility will be presented.

Short Biography

Professor Bartlett has been a principal contributor to the development of safety provisions in structural standards, including CSA S6 “Canadian Highway Bridge Design Code” and, more recently, the National Building Code of Canada and CSA A23.3 “Design of Concrete Structures”. Working for Buckland & Taylor Ltd., Vancouver, he was Project Engineer for the development of the Existing Bridge Evaluation criteria in the 1990 CSA S6 Standard, and later, with MKM Consultants, determined unique load and resistance factors for the Confederation Bridge to achieve the stringent target reliability levels and design life required. He is co-author, with James G. MacGregor, of “Reinforced Concrete: Design and Construction, First Canadian Edition. In 2002 he was elected Chair of the Structures Division of the Canadian Society for Civil Engineering.
